The past four to five decades have seen a remarkable reduction in the amount of time and effort required for the purification and characterization of biologically active peptides from animal tissues ...

This paper describes a unique Prep-rP-HPLC technique that uses a C-18/C-8 derivatized silica coated with a hydrophobic quaternary ammonium salt or quaternary phosphonium salt that acts as an ...

This is the second article in this series discussing HPLC oligonucleotide separations. This article will discuss the separation of oligonucleotides and dsDNAs using a wide-pore, polymer based reversed ...

High performance liquid chromatography, more commonly known by the acronym HPLC, is a method used to identify substances in a mixture. There are several types of HPLC, such as reversed-phase, ...

Chromatography of charged analytes is often challenging as they are not retained effectively on the commonly used reversed phase columns and elute in the dead volume. On columns with polar or aqueous ...

High-performance liquid chromatography or high-pressure liquid chromatography (HPLC) is a chromatographic method that is used to separate a mixture of compounds in analytical chemistry and ...
